Exempel på hur man kan använda PROTANDROUS i en mening

• In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), and bidirectional (serial or bidirectional hermaphroditism).
• All anemonefish are protandrous hermaphrodites, meaning they first develop into males and may become females later in life.
• The plants have protandrous dichogamy, this is because the male flowers, located at the end of the rachillae flower first, with the female flowers in the centre of the inflorescence flowering after the male ones senesce, thus promoting outcrossing.
• Members of the snail family Pulmonata, which includes carboniferous land sails and some freshwater snails of the order Basommatophora, are protandrous hermaphrodites, meaning they are born male and later in life become female.
• Flowers are co-sexual, protandrous and dichogamous, meaning each umbel presents either stigmas or pollen.
• While protogynous fish are found within species dominated by larger males, protandrous fish are within large female dominant species, such as the clown fish (Amphiprion).
• This species is a protandrous hermaphrodite and colonies have both male and female zooids; each individual zooid starts its existence as a male and later becomes a female.
• Though previously assumed to be gonochoristic, since eggs or sperm (but not both) can be found on the body wall of sexually mature adults, there are now observations of at least 3 species' life cycles in Diopatra known to be protandrous sequential hermaphrodites, indicating it is likely more widespread within the genus, especially since previous accounts suggesting gonochorism do not observe the entire life cycle of the worm.
